Abstract

A radio communication system comprises: a radio receiver (20) including an interference canceller (25) configured to generate a replica of a received signal and remove an interference signal from the received signal, and a frequency offset estimator (26) configured to estimate a carrier frequency offset between a carrier frequency of the interference signal and a carrier frequency of a desired signal included in the received signal; and a radio transmitter (10) including a frequency controller configured to adjust a carrier frequency of a transmitted desired signal to the carrier frequency of the interference signal based on the carrier frequency offset received from the radio receiver.
